Beryl (Henley) Mercer was active and influential in the BSFA and British fandom of the 60s and early 70s. She wrote some reviews for the BSFAfanzineVector and con reports, sometimes in conjunction with her husband, Archie Mercer. (In the early 60s, she published an article in Point of View on new fans' gripes about the BSFA; the opposing viewpoint was written by one Archie Mercer.)
